Planned Work

[zachghiaccio]

Currently working with the ICESat-2 snow depth tutorial in the Snow Cookbook, which also exists in the ICESat-2 cookbook. Trying to access a high-res snow-off DEM and an associated snow depth raster, but streaming it through earthaccess and loading it into memory is crashing my CryoCloud kernel. This is happening even when spatially subsetting and coarsening the data with ~4 GB of memory allocation.

Going to explore other options, including greater CryoCloud memory allocation, using the SnowEx database, or (last resort) downloading the data into a temp folder, then deleting after processing.
